I am going to eventually buy HP Tuners and was wondering of this lean cruise mode was even possible.

Looks like they deleted that thread just recently. It was there yesterday but not now.
Buy the way it was going, it looked like they almost had it work by modifing the checksums and whatnot.
Looks like they may have pushed the envelope about whats legal to talk about in the forums and someone whacked it.
